Actually, no; the mask at this point could just be a stream of ones and zeroes, representing
on/off for given squares. If we have an 11x11 screen, it would take 121 bits to mask the entire
screen. That translates to a 16-byte number (on the same line as the NEWMAP command)
representing the screen. On an n x m screen, this means the total number of bytes (B)
required is:
B = ceil((n x m) / 8)

Okay, so the server gives the client exactly what it sees. Hmmm. So, does the client do an
automatic SHIFT of the map? Let's forget LOS for the moment, and focus on what you're
proposing. In a large, open area (such as Scorn), would you be transmitting the MAP
command for all squares, or does the client do this implicit SHIFT? Okay, so now when we
head north from the starting area toward the wall, the top area of the sreen in not visible; when
the client does the implicit SHIFT, does it automatically assume the new area is *outside* the
LOS, consequently leaving the area black?
